Ultrasound

In women with nipple discharge, contrast breast MR has higheroverall sensitivity for detecting malignant and high-risk lesionsthan mammography or ultrasound.

A new survey from InMedica revealed over half of cardiologists surveyed across Russia and Eastern Europe had not received training on how to get the best use of their ultrasound imaging equipment. The situation was only slightly better for those working in general imaging, where approximately 40% had not received training on how to get the best use of their equipment.

The exhibition booths occupied by vendors of ultrasound systems at ECR 2010 are likely to be very busy places throughout the congress. Difficult economic conditions are causing a dip in global demand for the more capital-intensive modalities like CT and MRI, and hospital managers are keen for their staff to explore the clinical potential of this versatile and cost-effective technology.

Too few younger practicing radiologists are prepared to embrace ultrasound and push it to its clinical limits, according to Prof. Lorenzo Derchi, a professor of radiology at the University of Genoa in Italy.

Physicians have used palpation regularly as a diagnostic technique since the days of the ancient Greeks. Up to now, the potential value of this method has been explored in the imaging field only by ultrasound research teams, but at this year’s ECR technical exhibition, delegates can see for themselves how the same principles may be combined with MRI to improve diagnosis in patients with liver disease.

Measuring the fetal zone of the adrenal gland is a better predictor of preterm birth than measuring cervical length, according to research presented at the Society For Maternal-Fetal Medicine Feb. 4.

Sixteen years on from implementation of the Pre-Conception (PC) and Pre-Natal Diagnostic Techniques (PNDT) Act, burdensome bureaucracy penalizes many law-abiding radiologists in India. Furthermore, rather than preventing them, the act has driven up the price of illegal sex selection services. Meanwhile, registered ultrasound clinics face heavy fines for minor infringements.

Breast ultrasound is having its moment. Multiple scientific presentations at the RSNA 2009 meeting showed how careful use of ultrasound could allow imagers to so precisely characterize lesions that women could avoid biopsies.

Rheumatoid arthritis is a chronic and progressive inflammatory disease of the joints. It affects approximately 1% of the general population, with incidence being three times higher in women than men.

Breast cancer is one of the leading causes of cancer death among women. The risk of breast cancer typically increases with age in most countries.

Recent news coverage makes it seem as if women at high risk for breast cancer are refusing breast MRI screening left and right. That’s simply not the case, according to several experts.

Ultrasound elastography may be the link bridging the gap between suspicion and definitive proof, a noninvasive means to distinguish between benign and malignant tissue. The technology for doing so appeared some years ago at the annual meeting of the RSNA as an experimental curiosity. It’s been evolving since then until it appears now to have reached a clinical tipping point.

Though generally deemed safe, high-intensity focused-ultrasound ablation of liver and pancreas cancers can lead to delayed complications. According to Korean researchers, practitioners should be aware of-and watch closely for-local and systemic post-HIFU side effects several years down the road.

New ideas take time to catch on in medical imaging, whether they are brand new modalities, such as MR, or new techniques within an established modality, such as color Doppler ultrasound. It’s as though there are dues to be paid. Elastography appears to have paid its dues.

For many years, ultrasound has had a defined and very limited role in breast evaluations, being used for neither diagnosis nor detection.

Breast cancer detection rates increase substantially when women at high risk and those with dense breasts undergo mammography and ultrasound annually, according to a study presented Wednesday at the 2009 RSNA meeting. MRI is an even more effective technique when used with mammography, but only for women who are at high risk for the condition.

In an ironic twist for radiology, effective imaging of skin cancers has just been accomplished by none other than the imaging modality in closest contact with the skin: ultrasound.

Targeted breast ultrasound is less invasive and expensive than biopsy, as well as reduces anxiety over breast cancer screening.

SuperSonic Imagine returned to the RSNA exhibit floor with FDA clearance to market its Aixplorer ultrasound system in the U.S.

Ultrasound elastography could be an effective means of reducing unnecessary breast biopsy, according to an ongoing study presented Monday at the 2009 RSNA meeting.

GE Healthcare unveiled at RSNA 2009 a software technique that uses low-frequency sound waves in combination with MRI to measure the elasticity of liver tissue as an indicator of disease.

Despite challenges, ultrasound remains useful in obese trauma patients. Using the lowest frequency ultrasound probe along with tissue harmonic imaging improves image quality, according to an education exhibit presented at RSNA 2009.

Researchers in Germany and the Netherlands have discovered ultrasound- based patterns that can accurately diagnose the presence and stage of metastases in patients with melanoma.

Hand-carried ultrasound vendor SonoSite expanded its SonoAccess iPhone application to include resource materials for musculoskeletal specialties.
